Abstract
An optical source emits a source optical signal having a source optical signal power and a wavelength. A splitter or other similar device splits the source optical signal into a first optical signal having a first optical signal power and into a second optical signal having a second optical signal power such that the source optical signal power is split between the first optical signal power and the second optical signal power. This split is dependent upon the wavelength of the source optical signal. A first detector detects the first optical signal power and a second detector detects the second optical signal power. A controller responds to the first and second detectors in order to control the wavelength of the source optical signal.
